虚実 (Xū Shí) — The Void and the Real

In the world of Mahouka, magicians rewrite physics. But physics has rules — and the rules have authors. When Japan's Ten Master Clans violate an ancient protocol by conducting unsanctioned human experimentation and harvesting primordial spirits from the deep ocean, a hidden organisation older than any nation-state comes to collect what is owed. The Prime Minister — a figurehead kept ignorant by design — receives a visitor who walks through seven layers of magical security like fog. The Emperor already knows, and has chosen silence. A political thriller about sovereignty, power, and the categorical difference between playing within the rules and rewriting them. Mahouka Koukou no Rettousei AU. Xianxia cosmology. Adult themes. No harem. No power fantasy. The overpowered protagonist is the antagonist's problem, and the protagonist is a bureaucrat with a jade disc and nothing left to lose.
